The pedicel of cantaloupe itself is a little bitter, because there are bitter elements in the pedicel of cantaloupe. These bitter elements are to prevent cantaloupe from being invaded by pests and to better protect cantaloupe, so just don't eat the pedicel when eating.

There is another reason why cantaloupes are bitter: many cantaloupes on the market are not naturally ripe, but merchants add ripening agents to cantaloupes, which can make cantaloupes ripen quickly. The sugar content in the flesh of cantaloupes ripened by ripening agents is not enough, so you will feel some bitterness during eating.
